May I ask where you are getting these people at? I ask because rarely will people just complete an offer at random or just because you ask them to. To get people to do things for you, you will need to provide value... I have noticed that many people completely miss this little detail.

Now the way I do it is ask myself "Would I take 10 minutes of my time and give out my personal information for this?"
And if the answer is no, then I rework my niche and make sure to keep adding value until I can answer yes to that question.

So take a look at what you are offering and see if you can get that CR % up!
